Capture and replay ip network traffic

Overview

GL's Packet Recorder and Playback application can record and playback Ethernet and IP traffic up to 10 Gbps. It allows Playback and Record modes of operation simultaneously. In Record mode, high speed real-time traffic can be recorded with precise hardware time stamping. The Record feature includes a powerful Hardware Filter that allows users to filter out unwanted traffic, and continuously capture the traffic of interest up to the limits of the hard disk size and the disk write speed. The application supports file formats such as PCAP (Wireshark® format).

In Playback mode, you can re-transmit recorded traffic on selected network interface ports and analyze the traffic replay using packet analyzers such as GL's PacketScan™. Live traffic captured on a network using the Recorder utility, PacketScan™, or Wireshark® can be easily recreated in the lab.

The Packet Recorder and Playback application is an add-on software with GL's PacketScan™ HD network appliance. PacketScan™ HD is a high speed Ethernet packet capture appliance with large RAM and storage capacity and powerful protocol analysis software.


Main Features

  • Packet Recorder:
    • Captures 100% packet data on high speed lines (maximum of 5 Gbps data rate)
    • Capture packets non-intrusively over Ethernet (Electrical) and Optical ports at Nano-second precision
    • Recording can be done on single port or combination of one or more ports. Multiple instances of recorder can run simultaneously
    • Flexible options to record traffic continuously based on File size, File count, Frame count and Duration
    • Record only traffic-of-interest by applying efficient hardware filters based on MAC, 802.1Q (VLANs), IPv4/IPv6, Tunnel Traffic (Tunnel 1 and Tunnel 2), TCP, UDP, SCTP, SIP, and RTP parameters
    • Filter on inner layer of GTP, GRE, and VXLAN tunnel traffic like inner IPv4/IPv6 addresses and Transport Protocols (UDP, TCP and SCTP) port numbers
    • User can create their own filters using custom filter option which provides flexibility to check the fields and use the logical AND, OR conditions more efficiently
    • Option to view the historical graph of overall rate, frames/sec, per-port rate, per-port frames/sec, and Port Down status from the record start time to end time
    • Supports both IPv4 and IPv6
    • Provides statistics of captured frame count, dropped frame count, recorded frame count capture rate, frame rate, recorded files count, and more
  • Playback File:
    • Playback the pre-recorded traffic files at the same rate at which it is captured (maximum of 5 Gbps data rate)
    • Provides options to playback single file or multiple sequential files
    • Provides statistics of total frames transmitted, under sized frames count, oversized frames count and different sized frame count etc.
  • Provides general statistics, per port statistics and aggregated statistics to help check the progress of the recorder and playback operations

Hardware Filters

Supports defining up to 10 filters at Layer 2, 3, 4, and 5

  • MAC: Frames can be filtered out based on Source MAC address, destination MAC address, Ether Type and FCS Error
  • VLAN 0, 1, 2: Filters frames based on Tag protocol ID, User Priority, CFI, and VLAN ID
  • IPV4: Frames can be filtered based on Source IP Address, Destination IP Address, Protocol Type, Header Length, Differentiated Services, Ds_ECN, DS_CodePoint, Total Length, Check Sum Error, IP Datagram ID, Fragmentation Offset, Flag_DontFragment and Flag_MoreFragments
  • Tunnel Traffic: Tunnel filter provides a method to filter the packets of one protocol within another protocol. GTP, GRE and VXLAN are available tunneling methods. Hardware filters can be applied to Tunnel 1 and Tunnel 2 layers
  • IPv6: Frames can be filtered based on Source IP address, Destination IP address, Next Header, and Payload Length
  • ARP: Frames can be filtered based on Sender MAC Address, Target MAC Address, Sender IP Address, Target IP Address and Option Code
  • TCP: In TCP layer Frames, can be filtered based on source port, destination port and check sum error
  • UDP: In UDP layer Frames can be filtered based on source port, destination port, check sum error, UDP length and payload. For more details, refer to
  • SCTP: SCTP packets can also be filtered based on source port or destination port
  • SIP and RTP: SIP and RTP packets can also be filtered based on source port or destination port

PacketRecorder™ Application

Recorder application provides various options to capture the high density real-time traffic and store the recorded traffic into a file.

The number of recorded files can be saved sequentially or with Timestamp.

The application can capture the traffic continuously until user stops the recorder. The recorder can be stopped automatically after creating specified number of files, or the traffic can be over-written by keeping latest number of files.

Recorder Application

Hardware Filters

User interested traffic can be filtered using Hardware Filter option.

Example: Filtering SIP and RTP Traffic

The below Hardware Filter expression filters SIP packets runs over standard UDP port 5060 and filters RTP packets on even ports after port number 1023.

Example - Filtering HTTP Packets

Applying filters on TCP Source and destination ports can filter HTTP packets. In this example the TCP Source and destination port value is set to ’80’ for HTTP and ‘443’ for HTTPS. This will capture either of the packets whichever is True.
